Yes, far more nicotine. If your vape juice has 20 mg of nicotine per ml, about 1 - 2 mg of nicotine will be absorbed in a single puff. A cigarette will deliver about 2 mg of nicotine total. So hitting a vape 5 times can have the equivalent dose of nicotine of smoking 10 cigarettes. When I vaped for the first time I got dizzy like I hadn't gotten in years.

This might sound bad but it isn't really as much of a problem as you might think. Your body develops a tolerance to nicotine quickly so very soon it ceases affect your cardiovascular system any differently than a smaller dose would. It's just more addictive.

The greatest (known) danger from vaping that I know of is dental decay. PG and VG dry out your mouth which creates an environment ideal for bacteria. I've taken to using mouthwash in addition to brushing and flossing.

There is the possibility that there are unknown health risks. PG and VG are safe to consume orally, but chronic inhalation of these substances had never been attempted before vaping was invented. So we have no idea what it will do. However, given that 90% of lifelong smokers will get cancer at some point, vaping would have to be really bad to top that. It's a bit of a gamble, and I'm placing my bets that lifelong vaping will be less dangerous than lifelong smoking.

If you don't use nicotine, don't start. If you smoke cigarettes, quit. If you fail at quitting, try again, and again, and again. Only then if you can't should you take up vaping. I'm going to try to quit vaping in the near future.
